Title: Ignitor for internal-combustion engine
Inventor: TOYAMA KOUICHI
IPC: F02P3/045
Filed: 1984-02-06
Abstract: PURPOSE:To prevent erroneous operation by providing a whisker-shaped voltage for a standard voltage, synchronized with the start of electric conduction by using a condenser and a resistor and offsetting the whisker-shaped voltage supplied form a condenser for preventing oscillation. CONSTITUTION:When the electric conduction of a transistor 8 is cut-off by the output of a wave-form shaping circuit 2, an output transistor 17 is brought into conduction, and a charging electric current flows into a condenser 15 through a resistor 11 in a feedback circuit. Though a whisker-shaped voltage having the wave form shown by the full line is generated by the voltage drop of a resistor 14, etc. due to the charging electric current, a whisker-shaped electric current having the wave form shown by the broken line due to the charging electric wave for charging a condenser 54 is applied onto the standard side of the differential amplification of a current detecting circuit 20 from a correcting circuit 50, and erroneous operation can be avoided. At the time point for constant-current control after the output transistor 17 is put into electric conduction, the potential at the connection point between the resistors 31 and 33 of a detection circuit 30 does not vary and is constant, as shown by the broken line, since the condenser 54 is sufficiently charged, and a bad influence is not given onto constant- current operation.

IPC: B41L13/14
Filed: 1988-01-29
Abstract: PURPOSE:To enable a stencil paper being taken out to be securely wound around a plate- discharging roller, by mounting a fixed clamp and a movable clamp piece on the surface of a plate cylinder, fastening one end of a stencil paper between the fixed clamp and the movable clamp piece, wrapping the stencil paper around the plate cylinder, and releasing the stencil paper through scraping it by rubber-like elastic vanes extended radially from the plate discharging roller at a predetermined plate-discharging position. CONSTITUTION:One end of a stencil paper 16 is clamped between a movable clamp piece 4 and a fixed clamp surface 5. The stencil paper 16 is folded back along a leading end part of the movable clamp piece 4, is extended over the back surface of the movable clamp piece 4 to the rear side in the rotating direction of a plate cylinder 1, and is brought into close contact with the outer peripheral surface of the cylinder 1. Starting from this condition, the movable clamp piece 4 reaches a stencil paper discharging position, at which it is energized in an opening direction by an energizing means 8, and is pressed against one 14' of a pair of plate-discharging rollers which is located on the follow-up side of the rotating direction of the cylinder 1. At this time, rubber-like elastic vanes 18 of the other plate-discharging roller 14'' presses the movable clamp piece together with the stencil paper. Further, with both of the rollers 14', 14'' rotated, the vanes 18 cooperates with the roller 14' in pinching off the stencil paper 16 from the movable clamp piece 4 and wrapping the stencil paper 16 around the plate-discharging roller.

Abstract: PROBLEM TO BE SOLVED: To improve joining performance and reduce lowering of operating characteristics and restrike characteristics by specifying heating/cooling speed in assembling. SOLUTION: In a heating process when the end part of an insulating container in which a pair of electrodes are arranged in such a state as freely contacted/separated with each other and a sealing metal which seals the insulating container with a lid body are joined together, they are heated at the temperature increase speed of 1-20 deg.C/min from work temperature of 600 deg.C to brazing. In a cooling process, they are cooled at the cooling speed of 0.5-30 deg.C/min from brazing work temperature to 400 deg.C. This process can optimize heating/cooling conditions in assembling and improve the joining performance of the end face of the insulating container with the sealing metal via a silver brazing material.

Especially, at the time of over- discharge, in a range under a discharge potential of the active material 3, the layer 2 is changed by reduction reaction drastically from conductive material into insulation material, so it has effect of prohibiting electron conductivity in the over-discharge range. Flow of electrons is thus disconnected, and rupture or firing of the battery by an overcurrent can be prevented. Performance of the battery can thus be improved.
